Fruit and vegetables (F&V) are living tissues and highly perishable products needing optimal post-harvest technologies in order to maintain their storage stability and extend shelf life. The experiment was conducted in the winter months. Dried tomato slices ground to obtain powder. Dried powder was analyzed for its proximate composition that is moisture, crude fat, crude protein, crude fiber, ash, carbohydrates and energy. Nutritional characteristics of the dried powders were analyzed for proximate composition along with fresh fruit on dry weight basis. Results showed that fat, protein, ash content was found more in forced convection solar dried tomato. Color retention in forced solar dried powder found better when compared to natural convection solar dryer. Drying was also found faster in forced convection solar dryer. The benefit cost ratio in natural convection solar dryer for tomato was found to be 2.11 with a payback period of 2.53 years. The benefit cost ratio in forced convection solar dryer for tomato was found to be 2.91 with a payback period of 245 days. Hence, it can be inferred that the dryer is technically as well as economically feasible.
